A technical glitch has added to the nerves of students taking state tests this week as some school districts had trouble accessing the online testing sites Tuesday morning.

“During statewide testing today, some Mississippi testing sites experienced intermittent connectivity at some point between 9 a.m. and 10 a.m.,” said Jean Cook, a spokeswoman for the state Department of Education.

Madison County Superintendent Ronnie McGehee said students were unable to access tests due to an error with the Utah-based testing company Questar.
